Need port forwarding help on 6100D

I have a 6100D gateway with a public IP address (Sprint).  I've successfully set port forwarding for four ports on one internal IP address (192.168.1.20).

 

I've tried to forward two additional ports on a SECOND internal IP address (192.168.1.28).  I'm permitted to add the IP address and ports, but in a short time, the IP address is CHANGED by the router to the first IP address.   I don't know why the second IP address is not retained.  The port is retained.

 

I'm using DHCP with a DHCP pool of 10-50.  I'm using internal IP addresses of 20 and 28.  I set the IP address in the reservation area with their respective MAC address. 

 

What am I doing wrong?  Can someone help?

 

BTW, same results with Edge and IE browsers.

      I have not figured it out, BUT I have found a work-around that achieves my objective.

       

      First of all, the Netgear support was no help at all.  Three calls and three stupid answers:  try a different browser, try Chrome browser, try a different computer (!), reset the box.  I never talked to anyone who knew anything!  Always sandbagged by someone reading from a script.

       

      My 6100D eventually took a second IP address after reseting the box.  I needed three, but never got that.  My workaround was to swap my 2-port serial port server for a 4-port model, thus eliminating my need for the third IP address.  In my case that works to my satisfaction (asidde from the expense of the new server).

       

      I firmly believe there is a SW bug in the 6100D, but no one was willing to listen.

       

      BTW:  I started with Sprint support (my carrier), but that was a bigger joke.

       

      Maybe Chrome will help you.  Try a box reset.  Sneak up on it and it might work for you.  Sorry.

        Thanks for the reply.  Netgear and Sprint tech help was very tech-less and no help- like you said, scripted responses.  They say my unit should be replaced, but, like you, I think it is a software issue since several people have reported this problem.  I did a settings reset, but it did nothing.  I will try a facory reset next, and hopefully I can get a second IP to hold.  Thanks
